Routine Maintenance and Inspection
HOSE ASSEMBLY AND SAFETY:
If the hose shows signs of deterioration or damage, use a soap and water solution to test for leaks along the
entire outer surface of the hose while under pressure. Replace at the first sign of a leak or if age cracking becomes
apparent. Remember to turn the gas supply off before disconnecting. The hose must remain free of kinks and sharp
bends. Never puncture or put stress on the hose fittings. Replace the hose only with the manufactures original
equipment.
BURNERS:
The location of the burners to the main orifice is vital for safe operation. Check to assure the valve orifices are
inside the burner tubes before using the gas grill. If venturi of the burner is not correctly positioned over the valve
orifices, explosion and/or fire may occur when lighting the gas grill. Be careful not to damage the ceramic spark
electrodes.
Periodically inspect the burners for blockage or corrosion (see “Burner Cleaning”). Ensure that the aeration screw
is secure and that it is set properly. Be careful not to damage the ceramic electrodes

Remove Burners:
To remove the burners from the unit, first remove
the cooking grills (see Figure 21) and the flame
deflectors to access the burners. Undo the 1⁄4”
hex head bolt located on the rear of the inside
liner. Lift the back of the burner up slightly and
remove from the appliance (refer to Figure 31).
Install the burner in the reverse order and ensure
that the burner is placed over the orifice.
Burner Cleaning:
To keep your BISTRO working correctly, the
burners should be checked and cleaned on a
regular basis. To clean the burner tubes, first
remove the burner tubes from the barbecue
(refer to “Remove Burners”). Bend a stiff wire
(coat hanger will work) and run the hooked end
up through each venturi tube and into the burner
several times. Turn the burner upside down and
force water from a garden hose into the burner.
Observe the water flow from the holes in the
burner to make sure all holes have water coming
out. If not, continue to clean the burner by cleaning each individual obstructed hole. Use a wire brush on the outside
of the burner to remove any loose corrosion. Clean any holes with a stiff wire. If the burner has holes other than
the factory holes, replace the burner with the manufacturer’s original part. A clogged burner tube could cause a fire
beneath the gas grill.
